Alternatively, fluorescence in situ hybridization against Streptomyces strains could be applied (Kaltenpoth et al. Meloidogyne sp. It was isolated in 1966 by Umezawa et al. Many of these projects are focusing on the possibility to using genetic engineering to to create entirely new chemicals by splicing together machinery from the numerous templates provided by Streptomyces coelicolor. With the newly sequenced genome of Steptomyces coelicolor comes the possibility of deriving still more antibiotics that have so far remained undiscovered.
